WHIFFLETREE.

SPECIFICATION forming part of Letters Patent No. 226,896, dated April 27, 1880.

Application filed November 20, 1879.

To all whom it may concern:

Be it known that I, FREEMAN R. WILLSON, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in \Vhiffletrees; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

In the accompanying drawings, Figure 1 represents a perspective view of a complete Whiffletree embodying my invention. Fig. 2 represents a detail view of one of the wooden sections of the whiffletree. Fig. 3 represents the clip-casting which unites the two wooden sections in detail and interior view 5 and Fig. 4 represents, in detail, the draft-staple and the perforated disk to which it is attached.

In the accompanying drawings, A A designate two wooden sections, which constitute the wooden part of the whiffletree, and B designates an intermediate casting, which clasps the inner ends of said sections A A. This casting consists of a back having two perforations, b b, and side pieces, B B. These side pieces are slightly curved outward near the middle, and the inside of the back of said casting is circularly recessed. The inner ends of sections A A are similarly curved, so that a pocket of cylindrical form is made in the body of the whiffletree for the reception of the spring, hereinafter described.

This construction avoids the necessity of making the body of the whiffletree unduly thick by adding an exterior casting having a pocket.

Each section A A is provided near its inner end with a shoulder, a, which abuts against a stop-wall, B formed on the inside of casting B near the ends thereof.

cured in their places by nuts these rods D D help to hold the clip-casting B in proper position, and said clip-casting helps to hold said rods in proper position also. The general shape of said rods is similar to that of those embraced in my previous patent of February 25, 1879.

E designates two rigid fingers, cast with casting B, and extending forward from the inner face at the back of the same, so as to form guides for a perforated disk, F, which sets round them and in the circular recess at the back of the casting. This disk F has a flange, f, on its face, Fig.4, to afford a convenient brace for a helical spring, Gr, which sets on said disk around said flange.

H designates a draftstaple, which is surrounded by spring G, and is attached to disk F by nuts on the outside of said disk, which nuts can work through apertures 11 b of clipcasting B. The curved middle part of this staple is enlarged and is on the rear side of slotted plate I, which plate connects the aforesaid angular rods D D and forms a bearing for said spring. Bolts J extend through the side pieces of casting B and the inner ends of wooden sections A A. When these parts are all in position a very compact and neat whiffletree is produced.

The clip B (which, though described as a casting, is not necessarily such) effectually braces the wooden sections A A against all sorts of strain. Its stop-walls in particular relieve the strain on bolts J.

Any one of the parts may be easily replaced in case of injury without discarding the remainder of the article.

As a sp'ring-whiffletree the general action of the device is similar to that described in my patent of February 25, 1879 but the advantages of my new construction are obvious.

It is applicable equally to single-trees and to double-trees. When applied on single-trees to be attached to double-trees the draft-staple is removed and passed through the clip of the 5 double-tree, then back into the single-tree again, and attached as before. No other attachment is needed and no intervening link is required.

It is obvious that many changes of form I00 3. A whiffletree having its wooden part made in two sections, rigidly connected, with 15 an interposed space for the draft-spring, substantiaily as set forth.

In testimony that I claim the foregoing I have hereunto set my hand.

F. R. WILLSON.
